MECHANICAL AND BALLISTIC PROPERTY EVALUATIONS OF AROMATIC NYLONS FOR TRANSPARENT ARMOR APPLICATIONS

摘要

Thermal, mechanical and ballistic properties of two aromatic nylons, TROGAMID~® T-5000 (T-5000) and TROGAMID~® CX-7323 (CX-7323), were examined. Upon ballistic impact, T-5000 showed brittle failure similar to PMMA, while, CX-7323 exhibited ductile behavior similar to PC. Although these two materials show different failure behaviors, unlike PC and PMMA, overall behaviors of these two materials were similar each other. The ballistic impact resistance of these two aromatic nylons is noticeably better than PC and PMMA in wide range of thickness. The data obtained from flat plaque indicate that the improvement of ballistic resistance of these materials from the current fielded system could be significant on certain applications.
